Claims.

My invention particularly relates to improved forms of inserts adaptablefor mounting fine filamentous rayon thread in annular package form, suchas cakes, wound spools, wound bobbins, and other annular packages ofsymmetrical or balanced formation, for the purpose of liquid treatingthe thread. The rayon thread is collected in such annular package formsby spinning, machines from the precipitating bath in which the rayonfilaments are set up. The rayon thread as so collected comprises acomparatively large number of filaments which are twisted as some formsof packages are being collected and are collected untwisted in otherforms of packages. My invention is an improvement upon the forms ofpackage inserts shown, described and claimed in my pending application,Serial No. 724,114.

The treatments to which the rayon packages are subjected by my improvedapparatus are those to which the rayon is necessarily subjected, beforethe. precipitated and package-collected thread can be considered a finalproduct ready for the market, such as various water washingsdesulphurizing, bleaching, oiling, szing, dyeing, drying and otherpurifying and finishing operations. For purposesof illustration, I showin the accompanying drawing and herein describe two forms of my improvedinsert which serve to support a cake oi rayon while the same is beingsubjected to the above-mentioned operations.

The objects of the invention are to effect the aforesaid operations in athorough manner and economically, and without breaking or otherwisematerially damaging the thread, while at the same time preventing thecreation of any immobile areas in any portion of the package, or unequalstrains in different portions of the package, either during the liquidtreatments or during the drying of the package, which immobile areas andstrains result in a non-uniform dyeing of the thread of the package. Theobviating of the creation, of immobile areas and strained conditions inthe package produces even shrinkage during the drying of the package.This even shrinkage is obtained by even one drying operation, therebyobviating the necessity of rewetting the package and again. drying it inorder to improve the uniform shrinkage factor. Furthermore, if someportions of the package dry in an immobile condition, or have strainsset up therein by some of the purifying and drying operations,antecedently to the dyeing thereof, different portions of the thread inthe package then have different reflective indexes and give differentcolor reactions or have barred effects when the thread is dyed,resulting in a thread of non-uniform color.

Primarily, my improved insert effects the loosening up of the package,when treating the latter in its initial collected form, so as to providefor all parts of the package their respective natural scopes of freeplay, relative to other parts of the package, thus effecting a naturalalteration of the relative positions of all the thread strandscomprising the package. The purification of the package and the other,treatments thereof are carried out without unduly impairing the tenacityand elasticity of the thread required for later handling and processingor use, and without setting up local tension areas or non: uniformstrains.

In effecting the aforesaid advantage, my improved inserts permit thepulsating of the package body by means of treating liquid in that thepackage, while mounted upon. the insert, is free to move to apredetermined extentin, and under the action of, the treating liquid.The improved inserts provide for so mounting the package that differentportions thereof move or pulsate differently under the action of thetreating liquid; specifically, spaced transverse portions of the packagereact differently than the package portions intermediate said spacedtransverse portions.

Improved processes of liquid-treating rayon packages, and apparatustherefor, are shown, described and claimed in my pending application,Serial No. 724,113, and the improved inserts of the instant applicationare adaptable for use in working such processes. It is'designed in suchimproved processes that the direction of flow of i the treating liquidshall be, or at least may be,

periodically reversed, thus to pass the liquid alternately in bothdirections through the package body, from inside out and outside in, orat least the treating liquid penetrates the package body and tends topass through alternately in both directions. The treating liquid ispassed through the package body under any desired practicable pressureso as thereby to control to an extent the character of the treatment andthe character and amount of package movement and pulsation, and thepressure may be maintained uniform or may be varied. Although the rangeof practicable pressures is considerable, particularly by reason of thedifferent effects of dilierent treating liquids, I preferably use anominal pressure of from one to two pounds. My, improved inserts are ofsplit formation, so as to provide for the convenient insertion thereofwithin the rayon package, in order to mount the package thereon fortreatment without damaging the thread of the package, but the liquidpressures used in the liquid treatments are not great enough tomaterially expand or compress the split inserts, so that the latterprovide a substantially rigid support of constant dimension during theliquid treatments. Furthermore, as clearly shown and described in saidpending application, Serial No.

724,113, a plurality of inserts are tightly locked together in avertical tier, so as to hold the inserts rigid during the liquidtreatments, with a rayon package mounted for treatment on each one ofthe inserts.

When the treating liquid passes from without the tubular package throughthe body thereof and into the interior of the package, my improved.inserts provide for a deforming of the package by permitting portionsthereof to move inwardly a predetermined distance under the pressure ofthe treating liquid, so as to loosen up the package to a degree andpermit an altering of the positions of the strandsor different portionsof the thread comprising the package. When the treating liquid passesfrom within the package outwardly through the body thereof, the deformedpackage portions are moved back into their original collected form, ortend so to move, so that these package portions are pulsated or haveto-and-fro movements under the action of the reversible liquid flow. Itis. well understood by those skilled in the art, that rayon packages ofthe character herein described are spun so that the strands thereofprevent any substantial enlargement of the package perimeter. Therefore,the pressure of the treating liquid from within the package outwardly,under any pressures practicably usable, do not bulge or deform thepackage outwardly so as to increase its perimeter to any materialextent. package which are not moved inwardly by liquid passed inwardlyof the package body are adjusted somewhat outwardly during suchtreatment, as clearly shown in the accompanying drawing and as will behereinafter fully described. The improvements in the forms of insertsshown, describedv and claimed .in the instant application, over thoseshown, described and claimed in my said pending application, Serial No.724,114, consist in means for more uniformly liquid treating the rayonpackage, specifically, these improvements comprise means for permittingthe passage of the liquid through the insert. elements which define theseveral package portions that are difierently deformed by the treatingliquid. These elements, as shown in said application, Serial No.724,114, consist of insert bars, bobbin plates, etc., between eachadjacent two of which are provided elongated lengthwise openings throughwhich transversely spaced portions of the package defined by such barsand plates are pulsated. Radially exterior of these bars or plates arecertain package areas which do not receive efficient and satisfactoryliquid treatment. Therefore, I have devised forms of inserts shown anddescribed in theinstant application which provide for the passage ofliquid through the bodies of the spaced bars and plates whereby topermit the thorough liquid treatment of the rayon package areasimmediately exterior of such bars and plates.

The annexed drawing and the following description set forth in detailcertain means exemplifying my improved forms of package in- However,those portions of the is collected by the spinning machine or, if it hasbeen deformed by a treating liquid passed therethrough previously fromwithout the package inwardly, in the form in which it re-establishesitself or tends to be so re-established, when the treating liquidispassed through the cake from within outwardly;

Figure '7 is a view similar to Figure 6 but showing the forms assumed bythe different portions of the package body, or the forms which they tendto assume, when the treating liquid is passed through the package fromwithout inwardly. 7

Both forms of improved inserts shown and described provide for efiicientand satisfactory liquid treatment of those package areas radiallyexterior of the spaced bars and plates or equivalent means betweenadjacent deformable areas, but the claims of this application aredirected to that form of improved insert shown in Figures 1 to 4.

Referring to the annexed drawing in which the same parts are indicatedby the same re-- spective numbers in the different views, andparticularly referring to Figures 1-4,. an insert l consists of anannular shell having a multiplicity of ports 2 through the wall thereof,said ports preferably being arranged in a series of lengthwise rows anda series. of transverse rows, as clearly shown in Figure 1. These ports2 provide means for liquid communication between the interior andexterior of the shell body. Secured to the exterior surface of theinsert by rivets d are a plurality of non-corrosive bars 3. preferablyspaced longitudinal outwardly extended hard rubber bars. These spacedbars 3 provide spaced elongated lengthwise openings 8 between theadjacent bars 3 when a cake package I is mounted upon the bars 3. Whenthe treating liquid is passed through the package 7 from withoutinwardly the cake portions 9 between the respective adjacent bars It aremoved in wardly until they contact with the portions H of the insertbody. The portions ill of the cake body immediately exteriorly of thebars 3 cannot be moved inwardly but, in fact, adjust themselves slightlyoutwardly, as indicated by the areas I I, Figure 3. When the treatingliquid is passed through the package body I from within outwardly, thecake portions tend to re-establish themselves in the position shown inFigure 2. During the early stages of the liquid N treatment, the time orpressure of application thereof, or the density of the package body, maybe such, as not to permit entire penetration of the package body I bythe treating liquid, so that the package portions 9 will only tendtoward the positions shown therefor in Figures 2 and 3,

and the package portions II] likewise.

In order that the package areas I may receive liquid treatment uniformlywith the package portions 9, I provide the bars 3 with ports 5 whichhave liquid communication with the interior of the insert I and with thepackage body areas Ill. Preferably, I arrange the ports 5 to registerwith all of the ports in the adjacently lengthwise row of insert ports2. That is, the ports 5 of each of the bars 3 register with all of theports of one lengthwise row of ports 2 and with one of the ports of eachtransverse row of ports 2. Furthermore, I preferably enlarge the outerends of the ports 5 so as to provide ready and thorough distribution ofthe liquid from theports 5 into the package bodies 'I' when the liquidflow is from within outwardly and so as readily and thoroughly to directthe liquid flow from the pack-- age body I into the ports 5'when thedirection of the liquid flow is from without inwardly.

The several insert portions I2 formstops limiting the amount of inwardmovements of the cake portions .9.

By the means described, a thorough liquid.

treatment of the package portions I9 is secured, together with thethorough treatment of the package portions 9. i

In Figures 5, 6, and '7, I show a form of insert, preferably ofnon-corrosive metal, which is polygonal in cross-section and by the useof which are effected the advantageous liquid treatments contacts thecorners I91 of the insert, thus leave ing openings 29 between each twoadjacent corners I9, into which openings 29 the spaced pore tions 2| ofthe package I5' are forced by the pressure of a treating liquidpassedthrough the package from without inwardly, as clearly indicated inFigure 7, the areas 22 of the package I5,

which are adjacently exterior of the corners I9,

, being forced slightly outwardly during such ac- I tion, as indicatedby the areas 24, Figure '7. The

several plane insert portions 23 form stops limiting the amount ofinward movements of the package portions 2|. When the treating liquid ispassed through the package I5 from within the insert I6, the package I5tends to assume its original collectedfo-rm, as clearly indicated inFigure 6. The insert I6 is formed with a multiplicity of ports II, whichports are preferably arranged in a series of transverse rows and aseries of lengthwise rows, Figure 5. In order thatthe areas 22 of thepackage I5 may be efficiently liquid treated, as well as the spacedcomparatively large areas 2i, certain of the ports I! are disposed inthe angles I9 of the insert, as indicated by the ports I8. Preferably,one of the lengthwise rows ofports I1 is intersected by each angle I9 ofthe insert I5, and eachangle I9 also intersects one portof each ofthetransverse rows of ports. I'I.

By the means described, a thorough liquid treatment of the packageportions 22 is secured, together with the thorough treatment of thepackage portions 2L The pulsating of the rayon package duringliquid-treatment which is occasioned by the use of my improved packageinserts, and the consequent loosening-up and porosity of the package,give all portions of the latter full opportunity to contract whendrying, in accordance with their several tendencies, without occasioningany strain in any portion of the package. By pulsating I meantheinwardly and outwardly to and fro movements made by the package andthe constituent parts thereof during the liquid-treatment of the packageupon. my improved inserts.
